Chris Toomajian - Population and evolutionary genetics and genomics of plants and plant pathogens. Analyzes genome-scale DNA polymorphism datasets in order to infer the relative importance of processes such as mutation, recombination, genetic drift, migration, and natural selection in creating observed patterns of polymorphisms. Develops methods to infer recent instances of natural selection at the DNA level in order to identify adaptive genetic variation. Is interested in methods and datasets that allow for the statistical mapping of quantitative trait loci (complex traits) back to the genome in samples of unrelated individuals.
